Description

本発明は、例えば、重合槽から抜き出される芳香族ポリエステル等の重合物のように、固化しやすい高温液状物を移送するのに適した移送装置に関する。   The present invention relates to a transfer device suitable for transferring a high-temperature liquid material that easily solidifies, such as a polymer such as aromatic polyester extracted from a polymerization tank.

ポリエチレンテレフタラートやポリブチレンテレフタラートなどの結晶性ポリエステルやｐ−安息香酸を一成分とする結晶性ポリエステルが、耐熱性、耐溶剤性に優れることから、各種電子部品や工業部品に用いられている。一般に、結晶性ポリエステルである芳香族ポリエステルの重合反応過程においては、撹拌しながら重合を進めていくと反応系の粘度が上昇していき、撹拌負荷が大きくなり、さらに撹拌を続けることが困難になる。そこで重合反応の途中で芳香族ポリエステルのプレポリマーを重合槽から抜き取り、冷却固化した後、必要に応じて粉砕して、これを再度加熱して重縮合反応を完結させる方法が採用される。   Crystalline polyesters such as polyethylene terephthalate and polybutylene terephthalate and crystalline polyesters containing p-benzoic acid as one component are excellent in heat resistance and solvent resistance, and are used in various electronic parts and industrial parts. . In general, in the polymerization reaction process of aromatic polyester, which is a crystalline polyester, if the polymerization proceeds while stirring, the viscosity of the reaction system increases, the stirring load increases, and further stirring is difficult. Become. Therefore, a method is employed in which the prepolymer of the aromatic polyester is extracted from the polymerization tank in the middle of the polymerization reaction, cooled and solidified, and then pulverized as necessary, and then heated again to complete the polycondensation reaction.

芳香族ポリエステルは温度低下によって速やかに粘度上昇し、固化するという性質を有する。そのためプレ重合槽（以下、単に重合槽という）からダブルベルト式クーラ（以下、ベルトクーラという）へ芳香族ポリエステルを移送させるときは、重合槽から抜き出した芳香族ポリエステルを直ちにベルトクーラへ送るのが好ましい（特許文献１参照）。しかし、通常は図５に示すように１基のベルトクーラ３２に対して２基の重合槽３０、３１が設置され、交互にベルトクーラへ芳香族ポリエステルを移送している。そのため少なくとも一方の重合槽３１はベルトクーラ３２の入口側から離れた位置に配置せざるを得ないため、移送手段３４を必要とする。   Aromatic polyesters have the property of rapidly increasing in viscosity and solidifying with a decrease in temperature. Therefore, when the aromatic polyester is transferred from the prepolymerization tank (hereinafter simply referred to as the polymerization tank) to the double belt type cooler (hereinafter referred to as the belt cooler), the aromatic polyester extracted from the polymerization tank is immediately sent to the belt cooler. Preferred (see Patent Document 1). However, normally, as shown in FIG. 5, two polymerization tanks 30 and 31 are installed for one belt cooler 32, and the aromatic polyester is alternately transferred to the belt cooler. For this reason, at least one of the polymerization tanks 31 must be disposed at a position away from the inlet side of the belt cooler 32, and therefore requires a transfer means 34.

そこで、従来は芳香族ポリエステルの移送中にパイプ内部を流れる芳香族ポリエステルの温度が低下して固化しないように、芳香族ポリエステルを流すための内管を熱媒ジャケットで被覆した熱媒２重管を用いて芳香族ポリエステルを移送している。そして移送された芳香族ポリエステルはベルトクーラ３２で冷却固化され、粉砕機３３で粉砕されている。
特開平６−２５６４８５号公報 Therefore, conventionally, a heat medium double pipe in which the inner pipe for flowing the aromatic polyester is covered with a heat medium jacket so that the temperature of the aromatic polyester flowing inside the pipe is not lowered and solidified during the transfer of the aromatic polyester. Aromatic polyester is transferred using The transferred aromatic polyester is cooled and solidified by a belt cooler 32 and pulverized by a pulverizer 33.
JP-A-6-256485

前述のような熱媒２重管を用いて芳香族ポリエステルを移送させた場合、芳香族ポリエステルの固化物が徐々に内管の内壁面に付着するため、内管内の掃除が必要となる。ところが、熱媒２重管はそのままでは内管の掃除ができないために内管を取り外す必要があるが、その取り外しは困難である。   When the aromatic polyester is transferred using the above-described heat medium double tube, the solidified product of the aromatic polyester gradually adheres to the inner wall surface of the inner tube, and thus the inner tube needs to be cleaned. However, since the inner pipe cannot be cleaned with the heat medium double pipe as it is, it is necessary to remove the inner pipe, but it is difficult to remove the inner pipe.

一方、掃除をしやすくするために、前記熱媒２重管に代えて、上部開放部を蓋で覆い、下部に熱媒ジャケットを装着した樋を用いて芳香族ポリエステルを移送することが提案されている。しかし芳香族ポリエステルの移送中や樋の掃除中に、芳香族ポリエステルの中に異物が混入しやすい。また、移送中に芳香族ポリエステルが樋の上部開放部より放熱することで芳香族ポリエステルが固化しやすく、樋に付着した固化物が芳香族ポリエステルの流れを阻害するという問題がある。そのため定期的な樋の掃除が必要となり、この掃除のために製造装置を止めることで生産効率の低下を招いている。   On the other hand, in order to facilitate cleaning, it has been proposed to transfer the aromatic polyester using a scissor with the upper open part covered with a lid and a heat medium jacket attached to the lower part instead of the heat medium double pipe. ing. However, foreign substances are likely to be mixed into the aromatic polyester during the transfer of the aromatic polyester or during the cleaning of the basket. Further, there is a problem that the aromatic polyester is easily solidified by radiating heat from the upper open portion of the bag during the transfer, and the solidified material adhering to the bag hinders the flow of the aromatic polyester. Therefore, it is necessary to periodically clean the bag, and the production efficiency is lowered by stopping the manufacturing apparatus for this cleaning.

本発明は上記の問題に鑑みてなされたものであり、重合槽から抜き出された重合物などの固化しやすい高温液状物を移送する際に、該高温液状物が固化するのを抑制すると共に、たとえ移送装置内に固化物が堆積しても生産効率を低下させることがない高温液状物の移送装置を提供することを課題とする。   The present invention has been made in view of the above problems, and suppresses the solidification of the high-temperature liquid material when transferring a high-temperature liquid material that is easily solidified such as a polymer extracted from the polymerization tank. An object of the present invention is to provide a high-temperature liquid material transfer device that does not reduce the production efficiency even if a solidified material is deposited in the transfer device.

本発明に係る高温液状物の移送装置は、高温液状物を移送するパイプを筒形の保温用熱媒ジャケットに挿通し、かつ前記パイプを高温液状物の抜き出し口に着脱自在に接続したことを特徴とする。
前記熱媒ジャケットは、互いに重ね合わせて筒形となる一対の半割形熱媒ジャケット部材で構成されているのがよい。 The apparatus for transferring a high-temperature liquid material according to the present invention is such that a pipe for transferring the high-temperature liquid material is inserted into a cylindrical heat retaining heat medium jacket, and the pipe is detachably connected to the outlet for the high-temperature liquid material. Features.
The heat medium jacket may be composed of a pair of halved heat medium jacket members that are superposed on each other to form a cylindrical shape.

本発明において前記一対の両半割形熱媒ジャケット部材同士が、それらの側端部において蝶番で開閉自在に連結されているのがよい。また本発明では、前記パイプを内径４０ｍｍ以下のパイプにすることが好ましい。   In the present invention, the pair of both halved heat medium jacket members are preferably connected to each other at their side ends so as to be freely opened and closed by hinges. In the present invention, the pipe is preferably a pipe having an inner diameter of 40 mm or less.

前記高温液状物としては、例えば前記した重合槽から抜き出された芳香族ポリエステルなどの高温液状の重合物が挙げられるが、これのみに限定されるものではなく、各種の高温液状物にも同様に適用可能である。   Examples of the high temperature liquid material include, but are not limited to, high temperature liquid polymers such as aromatic polyester extracted from the above-described polymerization tank, and the same applies to various high temperature liquid materials. It is applicable to.

本発明によれば、前記パイプは熱媒ジャケットに挿通されており、前記高温液状物は熱媒によって保温されることによりパイプ内で固化しにくい。しかも、前記パイプは高温液状物の抜き出し口に着脱自在に接続されているので、パイプ内で高温液状物が固化した場合でも、新しいパイプと交換することができるので、生産効率を低下させることがない。   According to the present invention, the pipe is inserted into a heat medium jacket, and the high-temperature liquid material is hardly solidified in the pipe by being kept warm by the heat medium. Moreover, since the pipe is detachably connected to the outlet for the high temperature liquid material, even if the high temperature liquid material is solidified in the pipe, it can be replaced with a new pipe, which can reduce the production efficiency. Absent.

また、前記熱媒ジャケットが一対の半割形熱媒ジャケット部材で構成されている場合には、この半割形熱媒ジャケットを開いてパイプを取り外すことで、新しいパイプと簡単に取り替えることができ、さらに新しいパイプによって移送作業を行っている間に取り外したパイプの掃除を行うことができる。   In addition, when the heat medium jacket is composed of a pair of half-shaped heat medium jacket members, the pipe can be easily replaced with a new pipe by opening the half-shaped heat medium jacket and removing the pipe. In addition, the pipe removed during the transfer operation by the new pipe can be cleaned.

さらに、本発明によれば、前記パイプの内径を４０ｍｍ以下の小径とすることで、管内平均流速を速くし、これによりパイプの壁面に付着する固化物を少なくすることができる。   Furthermore, according to the present invention, by setting the inner diameter of the pipe to a small diameter of 40 mm or less, the average flow velocity in the pipe can be increased, thereby reducing the amount of solidified material adhering to the wall surface of the pipe.

以下、図面を参照しながら本発明の一実施形態に係る移送装置を説明する。図１は本発明の移送装置の一実施形態を示す概略側面図、図２は半割形熱媒ジャケット部材を開いた状態を示す横断面図、図３は上記移送装置に備えられたパイプの側面図、図４は上記パイプの入口側（流入側）の正面図である。   Hereinafter, a transfer device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic side view showing an embodiment of the transfer device of the present invention, FIG. 2 is a cross-sectional view showing a state where a half-shaped heat medium jacket member is opened, and FIG. 3 is a view of a pipe provided in the transfer device. 4 is a front view of the inlet side (inflow side) of the pipe.

この実施形態に係る移送装置は重合温度が３００℃以上の重合物である芳香族ポリエステルの製造装置において、重合槽の抜き出し口からベルトクーラまでの芳香族ポリエステルの流路に適用される。図１に示すように、重合槽の下部抜き出し口には、抜き出された高温の芳香族ポリエステル（高温液状物）中に混在する固化物を除去するためのろ過器１０と、このろ過器１０の排出管１９と結束バンド２３によって接続され移送方向の出口側が下となるように傾斜して配置された移送装置１１と、この移送装置１１に接続されたシュート１２とが芳香族ポリエステルの移送方向に沿って順に設けられている。また、例えば前述した図５に示すように、２基の重合槽の両方から交互に移送する場合は、各重合槽に対して移送装置１１、１１を配置し、各移送装置の出口側端部に設けられたフランジとシュート１２の熱媒ジャケット接続部分２８、２８とをボルトおよびナットで結合して接続すればよい。   The transfer device according to this embodiment is applied to the aromatic polyester flow path from the outlet of the polymerization tank to the belt cooler in an aromatic polyester production apparatus having a polymerization temperature of 300 ° C. or higher. As shown in FIG. 1, at the lower outlet of the polymerization tank, a filter 10 for removing solidified substances mixed in the extracted high-temperature aromatic polyester (high-temperature liquid), and the filter 10 The transfer device 11 connected by the discharge pipe 19 and the binding band 23 and arranged so as to be inclined so that the outlet side in the transfer direction is downward, and the chute 12 connected to the transfer device 11 are in the transfer direction of the aromatic polyester. Are provided in order. Further, for example, as shown in FIG. 5 described above, when alternately transferring from both of the two polymerization tanks, transfer apparatuses 11 and 11 are arranged for each polymerization tank, and the outlet side end of each transfer apparatus What is necessary is just to couple | bond and connect the flange provided in 1 and the heat-medium jacket connection parts 28 and 28 of the chute | shoot 12 with a volt | bolt and a nut.

移送装置１１は、図１、図２に示すように、一対の半割形熱媒ジャケット部材１３、１３からなる筒形の熱媒ジャケット２７にパイプ１４が挿通されている。そして半割形熱媒ジャケット部材１３は内周側に熱媒を流す管体１５を有しており、熱媒には、例えば、熱油などが使用される。そして熱媒を流す管体１５の外周を、例えば、ガラスウールなどの熱媒の放熱を防ぐための断熱材１６が覆っている。また、熱媒を流す管体１５には熱媒を流入させるための熱媒流入口２５が芳香族ポリエステルの移送方向の入口側に、流出させるための熱媒流出口２６が芳香族ポリエステルの移送方向の出口側にそれぞれ設けられている。熱媒ジャケット２７を構成する半割形熱媒ジャケット部材１３同士は接する側端部の一方を蝶番１７で、他方をアジャストファスナーなどの止め具１８によって固定されている。止め具１８としてはアジャストファスナーの他に、例えば、半割形熱媒ジャケット部材１３の側端部にフランジを設け、このフランジ同士をボルトおよびナットで結合して固定してもよい。   As shown in FIGS. 1 and 2, in the transfer device 11, the pipe 14 is inserted into a cylindrical heat medium jacket 27 including a pair of half-shaped heat medium jacket members 13 and 13. The half-shaped heat medium jacket member 13 has a tube body 15 for flowing the heat medium on the inner peripheral side, and for example, hot oil or the like is used as the heat medium. And the heat insulating material 16 for preventing the heat dissipation of heat media, such as glass wool, has covered the outer periphery of the pipe body 15 which flows a heat medium. In addition, the heat medium inlet 25 for allowing the heat medium to flow into the pipe body 15 through which the heat medium flows is provided on the inlet side in the transfer direction of the aromatic polyester, and the heat medium outlet 26 for allowing the heat medium to be transferred to the aromatic polyester. Provided on the exit side of the direction. The halved heat medium jacket members 13 constituting the heat medium jacket 27 are fixed to each other by a hinge 17 at one of the side end portions in contact with each other and a stopper 18 such as an adjust fastener. As the stopper 18, in addition to the adjust fastener, for example, a flange may be provided at a side end portion of the half-shaped heat medium jacket member 13, and the flanges may be coupled and fixed with bolts and nuts.

図３は、移送装置１１に挿通したパイプ１４を示している。このパイプ１４は、ろ過器１０の排出管１９と接続するために、一端部の径Ｗ２はろ過器の排出管１９の径と略同一の径となっているが、その他の部位は、パイプ１４内における芳香族ポリエステルの管内流速を高めるために、一端部の径Ｗ２に比べて径Ｗ１が小さくなっている。すなわちパイプ１４の径が絞られていることが好ましい。パイプ１４の径Ｗ１は熱媒ジャケット２７からの伝熱を高めるために熱媒ジャケットの内径の５０％以上であることが好ましく、具体的にはパイプの径Ｗ１は４０ｍｍ以下が好ましく、その中でもパイプの径Ｗ１は２５ｍｍ以下がより好ましい。
このようにパイプ１４の径Ｗ１を小径にしてパイプ１４内における芳香族ポリエステルの管内流速を速くすることで、移送装置１１内での芳香族ポリエステルのパイプ壁面付近での滞留を小さくし、粘度上昇を抑制できるため、パイプ１４内に付着する芳香族ポリエステルの固化量を抑制できる。具体的には、パイプ１４内の芳香族ポリエステルの管内平均流速を好ましくは０．５m／秒以上、より好ましくは１．０m／秒以上とするのがよい。 FIG. 3 shows the pipe 14 inserted through the transfer device 11. Since this pipe 14 is connected to the discharge pipe 19 of the filter 10, the diameter W2 at one end is substantially the same as the diameter of the discharge pipe 19 of the filter. In order to increase the flow rate of the aromatic polyester in the tube, the diameter W1 is smaller than the diameter W2 at one end. That is, it is preferable that the diameter of the pipe 14 is reduced. The diameter W1 of the pipe 14 is preferably 50% or more of the inner diameter of the heat medium jacket in order to enhance heat transfer from the heat medium jacket 27. Specifically, the diameter W1 of the pipe is preferably 40 mm or less. The diameter W1 is more preferably 25 mm or less.
In this way, by reducing the diameter W1 of the pipe 14 and increasing the flow rate of the aromatic polyester in the pipe 14, the retention of the aromatic polyester near the pipe wall surface in the transfer device 11 is reduced, and the viscosity is increased. Therefore, the solidification amount of the aromatic polyester adhering to the inside of the pipe 14 can be suppressed. Specifically, the average flow velocity of the aromatic polyester in the pipe 14 is preferably 0.5 m / second or more, more preferably 1.0 m / second or more.

図３および図４に示すようにパイプ１４の入口部分には、パイプ１４を熱媒ジャケット２７に設置する際に所定の設置位置に固定するためのアイボルト２０が挿通する挿通孔２９を備えたストッパー２１が設けられている。すなわち熱媒ジャケット２７は移送方向の出口側が下となるように傾斜して配置されているため、パイプ１４を熱媒ジャケット２７に設置する際にストッパー２１によってパイプ１４が傾斜方向に滑り落ちることを防ぐ。また、パイプ１４には熱媒ジャケット部材２７への着脱を容易にするために取手２２が取り付けられている。   As shown in FIGS. 3 and 4, a stopper provided with an insertion hole 29 through which an eyebolt 20 for fixing the pipe 14 to a predetermined installation position when the pipe 14 is installed in the heat medium jacket 27 is inserted in the inlet portion of the pipe 14. 21 is provided. That is, since the heat medium jacket 27 is inclined and disposed so that the outlet side in the transfer direction is downward, the stopper 14 prevents the pipe 14 from sliding down in the inclination direction when the pipe 14 is installed on the heat medium jacket 27. . Further, a handle 22 is attached to the pipe 14 in order to facilitate attachment and detachment to the heat medium jacket member 27.

図１に示すようにパイプ１４の入口側に接続されたろ過器１０は、重合槽の下端に接続され、芳香族ポリエステルに混在する固化物をろ過するための多数個の貫通孔を形成したパンチングプレート（図示せず）を内部に有し、パイプ１４に接続するための排出管１９を備えている。本実施形態においては上記のようにパイプ１４とろ過器１０の接続は結束バンド２３によって行われているが、結束バンド２３以外にろ過器の排出管１９の端部およびパイプ１４の入口側末端部分にそれぞれフランジを設け、このフランジ同士をボルトおよびナットで結合して接続してもよい。   As shown in FIG. 1, the filter 10 connected to the inlet side of the pipe 14 is connected to the lower end of the polymerization tank, and is punched with a large number of through holes for filtering the solidified material mixed in the aromatic polyester. A plate (not shown) is provided inside, and a discharge pipe 19 for connecting to the pipe 14 is provided. In the present embodiment, the pipe 14 and the filter 10 are connected by the binding band 23 as described above. In addition to the binding band 23, the end of the discharge pipe 19 of the filter and the inlet-side end portion of the pipe 14 are used. Each may be provided with a flange, and the flanges may be connected with a bolt and a nut.

パイプ１４の出口側に接続されたシュート１２は中空で、下面が開口してベルトクーラの導入部に臨んでいる直方体形のシュート本体部分と、シュート本体部分の側面および相対面にそれぞれ設けられた熱媒ジャケット接続部分２８、２８とを備えている。   The chute 12 connected to the outlet side of the pipe 14 is hollow, and is provided on each of a rectangular parallelepiped chute main body portion that is open at the lower surface and faces the introduction portion of the belt cooler, and a side surface and a relative surface of the chute main body portion. Heat medium jacket connection portions 28 and 28 are provided.

（重合物の移送方法）
芳香族ポリエステルは重合槽から抜き出され、重合槽の下端の出口に設けられた流量制御バルブ（図示せず）によって流量が調整される。なお流量制御バルブに代えてポンプにより重合槽から芳香族ポリエステルを取り出すようにしてもよい。 (Polymer transfer method)
The aromatic polyester is extracted from the polymerization tank, and the flow rate is adjusted by a flow control valve (not shown) provided at the outlet at the lower end of the polymerization tank. The aromatic polyester may be taken out from the polymerization tank by a pump instead of the flow rate control valve.

抜き出された芳香族ポリエステルはろ過器１０を通過することで、芳香族ポリエステル内の固形物がろ別される。そしてろ過された芳香族ポリエステルは移送装置１１を経由してシュート１２まで移送される。移送の際は半割形熱媒ジャケット部材１３内部に設けられた熱媒を流す管体１５に、芳香族ポリエステルの重合温度（通常、３００℃以上）と略同じ温度の熱媒を熱媒流入口２５から流入させ、熱媒流出口２６より排出させる。これによりパイプ１４内を移送中の芳香族ポリエステルは熱媒によって保温され、粘度上昇とそれによる固化を抑制できる。そして上記流量制御バルブによってパイプ１４内における芳香族ポリエステルの管内平均流速を前述の通り好ましくは０．５m／s以上、より好ましくは１．０m／s以上とすることで、パイプ１４内に付着する芳香族ポリエステルの固化量を抑制できる。   The extracted aromatic polyester passes through the filter 10 so that solids in the aromatic polyester are separated by filtration. The filtered aromatic polyester is transferred to the chute 12 via the transfer device 11. During the transfer, a heat medium having a temperature substantially equal to the polymerization temperature of the aromatic polyester (usually 300 ° C. or higher) is passed through the pipe body 15 through which the heat medium provided inside the half-shaped heat medium jacket member 13 flows. It flows from the inlet 25 and is discharged from the heat medium outlet 26. As a result, the aromatic polyester being transferred through the pipe 14 is kept warm by the heat medium, and an increase in viscosity and solidification caused thereby can be suppressed. Then, the average flow rate of the aromatic polyester in the pipe 14 is preferably 0.5 m / s or more, more preferably 1.0 m / s or more as described above, by the flow rate control valve so that the aromatic polyester adheres to the pipe 14. The solidification amount of the aromatic polyester can be suppressed.

流れてきた液状の芳香族ポリエステルはシュート１２に当たって、シュート１２の下に配置された冷却手段であるベルトクーラへと落下する。冷却手段としてダブルベルト式クーラに限定されるものではなく、シングルベルト式クーラ、すなわちベルト上に液状物を載置・搬送しながら冷却・固化する形式のベルトクーラであってもよい。ベルトクーラは、それぞれスチールベルトなどの耐食性を有する金属製の無端ベルトからなる上側ベルトと下側ベルトを上下に密接して配置し、上下のベルト間に芳香族ポリエステルを挟んで移送しながら冷却する装置である。   The flowing liquid aromatic polyester hits the chute 12 and falls to a belt cooler that is a cooling means disposed under the chute 12. The cooling means is not limited to a double belt type cooler, but may be a single belt type cooler, that is, a type of belt cooler that cools and solidifies while placing and conveying a liquid material on the belt. In the belt cooler, an upper belt and a lower belt made of metal endless belts each having corrosion resistance such as a steel belt are arranged in close contact with each other, and cooled while sandwiching an aromatic polyester between the upper and lower belts. Device.

（パイプの交換および掃除）
パイプ１４の内壁に付着した芳香族ポリエステルの固着物を掃除する際は、図１、図２に示すように、パイプ１４に設けられたアイボルト２０を熱媒ジャケット２７から外し、次にアジャストファスナー１８を外し、蝶番１７で連結された半割形熱媒ジャケット部材１３、１３を開き、さらに結束バンド２３を外してパイプ１４を取り外す。パイプ１４を取り外す際は取手２２を持って取り出す。そして掃除済みの新しいパイプ１４を装着することによって次の移送作業を即座に開始できる。さらに新しいパイプ１４によって移送作業を行っている間に取り外したパイプ１４の掃除を行うことで、芳香族ポリエステルの生産効率を低下させずにパイプ１４の掃除ができる。 (Pipe replacement and cleaning)
When cleaning the adhered matter of the aromatic polyester adhering to the inner wall of the pipe 14, as shown in FIGS. 1 and 2, the eyebolt 20 provided on the pipe 14 is removed from the heating medium jacket 27, and then the adjustment fastener 18 , The half-shaped heat medium jacket members 13 and 13 connected by the hinge 17 are opened, the binding band 23 is removed, and the pipe 14 is removed. When removing the pipe 14, hold the handle 22 and remove it. Then, the next transfer operation can be started immediately by installing a new pipe 14 that has been cleaned. Further, by cleaning the removed pipe 14 while the new pipe 14 is being transferred, the pipe 14 can be cleaned without reducing the production efficiency of the aromatic polyester.
